| Abstract | This paper presents applications where the DBEM formulations presented by Dirgantara and Aliabadi [3, 4] is combined with the multi region BEM presented recently by Baiz and Aliabadi [2], for the analysis of cracked shear deformable plates and shallow shell assemblies. Stress intensity factors are obtained using the CTOD technique. Several examples are solved to demonstrate the capabilities of the proposed technique. Comparing DBEM with FEM, it was clear that good accuracy and e􀀡ciency can be achieved with the present multi region DBEM. |
